摘要： The invention provides a method for producing low molecular weight polytetrafluoroethylene less likely to generate C8-C14 perfluorocarboxylic acids and salts thereof. The method for producing low molecular weight polytetrafluoroethylene includes: (1) feeding into an airtight container: polytetrafluoroethylene; at least one additive selected from the group consisting of hydrocarbons, chlorinated hydrocarbons, alcohols, and carboxylic acids other than C8-C14 perfluorocarboxylic acids; and at least one selected from the group consisting of inert gases other than the above additive and oxygen adsorbents; and (2) irradiating the polytetrafluoroethylene to provide low molecular weight polytetrafluoroethylene having a complex viscosity of 1 × 10 2 to 7 × 10 5 Pa·s at 380°C.

摘要： The invention provides a production method for producing low molecular weight polytetrafluoroethylene enabling easy removal of most of C8-C14 perfluorocarboxylic acids and salts thereof, which are unfortunately generated by irradiation, from the low molecular weight polytetrafluoroethylene. The method for producing low molecular weight polytetrafluoroethylene includes: (1) irradiating polytetrafluoroethylene to provide low molecular weight polytetrafluoroethylene having a melt viscosity of 1 × 10 2 to 7 × 10 5 Pa·s at 380°C; (2) pulverizing the low molecular weight polytetrafluoroethylene; and (3) heating the low molecular weight polytetrafluoroethylene pulverized in the step (2).
